Hopefully it will work. In end it looks like I could run it un-powered if need be. I know I don't have 8 TVs running in the house, but a set and forget is something I was hoping for.
And thanks for running those other looks at CBET. I had seen the antenna pattern and also figured earth curvature was a problem. Sometimes we can get a nice inversion layer over Lake Erie and we can see all sorts of strange things happen (like you can see the lights on the other side of the lake, but that is a rare occurrence and certainly not something I can count on.
